Bollywood couple Ajay Devgan and Kajol are all set to make a cameo in a song in Anil Devgan's next film 'Haal-E-Dil'.

'Myself and Kajol are shooting for Anil's upcoming film. It is just a guest appearance or cameo in a song, which we call a train song. It is quite nice and very fresh, ' Ajay wrote in his last blog entry.

Anil, who is Ajay's brother, has also directed the latter in 'Raju Chacha' and 'Blackmail'.

'Anil has worked really hard and the look of the film has also shaped up really nice. Hope Anil gets appreciated with 'Haal-E-Dil', ' Ajay said.

The song in the film, starring newcomers Amita Pathak, Adhyayan Suman and Nakuul Mehta, is titled 'Oye Hoye'.
